What about using <meta http-equiv="Refresh" content="60; http://yoururl">
in the header of the page?

As i understand it, this would try to grab a new copy of the page every
minute (modify the 60 if you want a longer or shorter time).  By keeping
track of when the reloads cease, you'd know when the visitor closed the
browser (or lost network connectivity) even if she/he didn't hit the logout
button.

And surely it'll be no picnic to integrate something like this with your
already existing authentication code (so that it works seamlessly and doesn't
demand a new login on every automatic refresh once a minute).  And if your
pages are places where people can input data (via forms), it'd be a real
drag to have the page automatically reload (and lose the paragraph or so of
text that your visitor just entered in a form field(s)).


	good luck,
